Answer:
![1/4x^{5}](https://tex.z-dn.net/?f=1%2F4x%5E%7B5%7D)
Step-by-step explanation:
Answer:
the percent of change is ![32.48\%](https://tex.z-dn.net/?f=32.48%5C%25)
Step-by-step explanation:
Step 1
Convert the time in seconds
![7:45=7*60+45=465\ sec](https://tex.z-dn.net/?f=7%3A45%3D7%2A60%2B45%3D465%5C%20sec)
![5:51=5*60+51=351\ sec](https://tex.z-dn.net/?f=5%3A51%3D5%2A60%2B51%3D351%5C%20sec)
we know that
----> represent the ![100\%](https://tex.z-dn.net/?f=100%5C%25)
Step 2
the change of the time is equal to
Step 3
by proportion
find the percent of change
![\frac{100}{351}=\frac{x}{114} \\ \\x=114*100/351\\ \\x=32.48\%](https://tex.z-dn.net/?f=%5Cfrac%7B100%7D%7B351%7D%3D%5Cfrac%7Bx%7D%7B114%7D%20%5C%5C%20%5C%5Cx%3D114%2A100%2F351%5C%5C%20%5C%5Cx%3D32.48%5C%25)

Answer:
The answer to your question is: 30 gallons / h
Step-by-step explanation:
Convert 2 quart/ min to gallons per hour
![\frac{2 quart}{min} x \frac{0.25 gallons}{1 quart} x \frac{60 min}{1 h}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20quart%7D%7Bmin%7D%20x%20%5Cfrac%7B0.25%20gallons%7D%7B1%20quart%7D%20%20x%20%5Cfrac%7B60%20min%7D%7B1%20h%7D)
![= \frac{2 x 0.25 x 60}{1x 1 x 1}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B2%20x%200.25%20x%2060%7D%7B1x%201%20x%201%7D)
= 30 gallons /h
Answer:
x = 4
y = 2
Step-by-step explanation:
by using substitution method ;
now, in second equation ;
- 2x + 3y = 14
- 2 (8 - 2y) + 3y = 14
( since x = 8-2y, from equation 1 )
- 16 - 4y + 3y = 14
- 16 - y = 14
- -y = 14 - 16
- -y = -2
- y = 2
<em>i</em><em> </em><em>hope</em><em> </em><em>it</em><em> </em><em>helped</em><em>.</em><em>.</em><em>.</em>
putting value of y in equation 1, we get :
- x + 2y = 8
- x + (2 × 2) = 8
- x + 4 = 8
- x = 8 - 4
- x = 4
